sítérület

A **sítérület** (also known as a *website* or *web domain*) refers to a unique internet address where a collection of related web pages, files, and other digital resources are hosted. It serves as the virtual address for a specific online presence, allowing users to access information via web browsers. Sítérületek consist of two main components: the **domain name** (e.g., "example") and the **top-level domain (TLD)** (e.g., ".hu" for Hungary, ".com" for commercial sites). Together, they form the full address, such as *example.hu*.

Domain names are registered through accredited registrars, ensuring exclusivity and preventing duplication. The underlying infrastructure relies on the **Domain Name System (DNS)**, which translates human-readable domain names into numerical **IP addresses** that computers use to locate and communicate with servers. Websites are typically hosted on servers managed by web hosting providers, which store the necessary files and ensure continuous accessibility.

Sítérületek can serve various purposes, including personal blogs, business portals, e-commerce platforms, or informational resources. They may also incorporate additional elements like subdomains (e.g., *blog.example.hu*) to organize content hierarchically. Security and maintenance are critical aspects, as websites must be protected against cyber threats and regularly updated to remain functional and user-friendly.

In Hungary, domain registrations are governed by regulations set by the **Hungarian Network Information Center (HU.NET)**, which oversees the **.hu** country-code top-level domain. Proper registration, maintenance, and adherence to legal requirements ensure a smooth and reliable online presence.
